[architecture] Inter-agent context lost or mutated during handoffs using free-form text

Enforce structured-schema \(JSON Schema/Pydantic\) message contracts for all inter-agent communication instead of natural language summaries.

Journey Context:
Developers often let agents summarize state for the next agent via natural language because it seems flexible. However, LLMs frequently omit critical parameters, hallucinate values, or alter formatting during these transitions. Structured schemas act as a hard contract, ensuring no state is dropped and the receiving agent gets exactly the typed data it expects, trading a bit of generation flexibility for deterministic reliability.
